INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented Jan. 19, 1915.

Application filed June 2, 1914. Serial No. 842,343.

To aZZ 'Uj/LU/YL it may concern.

Be it known that I, HUoo C. WELL, a subject of the Emperor of Germany, and a resident of the city of New York, borough of the Bronx, county of the Bronx, and State of New York, have invented a new and improved Internal Combustion Engine, of which the following is a full, clear, and exact description.

My invention has for its object to provide means for rotating a valve sleeve in a cylinder, the said means consisting of a crank operable by a piston rod and geared to the sleeve.

-additional objects of the invention will appear in the following specification in which the preferred form of my invention is disclosed.

In the drawings similar reference characters refer to similar parts in all the views in which" Figure 1 isa sectional elevation of an internal combustion engine provided with my improvement; and Figs. 2, 3, 4 and 5 are diagrammatic views showing the different positions of the valve sleeve relatively to the cylinder.

By referring to the drawings it will be seen that a cylinder is provided having an inlet port 11 for the hydrocarbon gas, an exhaust port 12 and an additional port 13 for introducing air to the cylinder, to assist in driving therefrom, the gases of comhustion. The cylinder 10 is provided with Disposed for rotatin in-the cylinder 10, and coaxially therewit there is a valve sleeve 15 which is provided with ports 16 for communicating with the port 11, ports 17 for communicating with the port 12 and ports 18 and 19 for communicating with the port 13.

It will be seen that the engine shown in the drawingsis of the four-cycle type and that the valve sleeve 15 makes a half revolution at each cycle of the engine.

In the sleeve 15 there is a piston 20 which is articulated to the piston rod 21, the

member 26, the arm 2 1 being held in operative position, in the said slot 23 by means of the springs 27 whichpress against the ends of the slot and also against the arm 21 and the nut 26, to hold the arm 2 1 yieldingly in position relatively to the ends of the said slot. This crank is journaled in a bearing in a casing 28-0f the engine and is provided with a gear wheel 29, this gear wheel 29 meshing with a gear 30 on the valve sleeve 15 so that with the operation of the engine, the valve sleeve will be 1'0- tated by means of the crank 25 of the gear 29.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

1. In aninternal combustion engine, a.

cylinder having a port, a sleeve for rotating coaxially with the cylinder and having a port for communicating with the port in the cylinder, a piston in the cylinder, a piston rod connected with the piston, a crank operable by the piston rod and gearing connecting the crank with the sleeve for operating the latter.

2. In an internal combustion engine, a cylinder having a'port, a sleeve for rotating coaxially with the cylinder and having a port for communicating with the port in the cylinder, a piston in the cylinder, a piston rod connected with the piston, a crank articulated to the piston rod, and gearing connecting the crank with the sleeve for operating the latter.

3. In an internal combustion engine, a

cylinder having a port, a sleeve for rotating coaxially with the cylinder and having a port for communicating with the port in the cylinder, a piston in the cylinder, a piston rod connected with the piston, there being a slot in the piston rod. a crank having an arm disposed in the slot, springs for holding the arm yieldingly in position in the slot and gearing connecting the crank with the sleeve for operating the latter.

In testimony whereof I have hereunto signed my name to this specification in the presence of the two undersigned witnesses.

HUGO WELL.
